doi:10.1146/annurev.biochem.71.083101.124707. Pol IV: a Y-family DNA polymerase. PMID5946628. ^ "The Nobel Prize in Physiology or Medicine 1959". World Scientific Publishing Company.

News Medical. ^ DNA polymerase v t e DNA replication (comparing Prokaryotic to Eukaryotic) Initiation Prokaryotic (initiation) Pre-replication complex dnaC Cdc6 Helicase dnaA dnaB T7 Primase dnaG Eukaryotic (preparation in G1 Nucleic Acids Res. 40 (6): 2611–22. The other members of group B do have at least one other subunit which makes the DNA Pol II unique.[10] Primary Cellular Function[edit] Confirmed[edit] Polymerases all are involved with DNA replication doi:10.1146/annurev.biochem.71.083101.124707.

doi:10.1016/S1876-1623(08)78004-0. Gefter in 1970 while further elucidating the role of Pol I in E. PMID13747134. ^ Zimmerman, B.K. (1966). "Purification and properties of deoxyribonucleic acid polymerase from Micrococcus lysodeikticus". Members of Family Y have five common motifs to aid in binding the substrate and primer terminus and they all include the typical right hand thumb, palm and finger domains with

The modern form of this mechanism depends on AID dC-to-dU lesions and long tract error-prone cDNA synthesis of the transcribed strand by DNA Polymerase-η acting as a reverse transcriptase. Cell Cycle. 6 (7): 817–22. doi:10.1111/j.1365-2958.2005.04805.x. Biochem.

U.S.A. 88 (24): 11197–201. DNA Pol II can proofread and process mismatches caused by the Pol III. PMID22820381. ^ Jarosz DF (2007). "Proficient accurate bypass of persistent DNA lesions by DinB DNA polymerases.". The average DNA polymerase requires about one second locating and binding a primer/template junction.

Pol δ: Highly processive and has proofreading 3'->5' exonuclease activity. When synthesizing new DNA, DNA polymerase can add free nucleotides only to the 3' end of the newly forming strand. Acad. Nobel Foundation.

This repair polymerase is involved in excision repair with both 3'-5' and 5'-3' exonuclease activity and processing of Okazaki fragments generated during lagging strand synthesis.[15] Pol I is the most abundant The shape can be described as resembling a right hand with thumb, finger, and palm domains. The 3'-5' exonuclease activity of the enzyme allows the incorrect base pair to be excised (this activity is known as proofreading). PMID18157155. ^ Zhang L, Chan SS, Wolff DJ (July 2011). "Mitochondrial disorders of DNA polymerase γ dysfunction: from anatomic to molecular pathology diagnosis".

Synthesis of a polymer of deoxyadenylate and deoxythymidylate". This difference enables the resultant double-strand DNA formed to be composed of two DNA strands that are antiparallel to each other. VII. Pol β: Implicated in repairing DNA, in base excision repair and gap-filling synthesis.

Mol. doi:10.1021/bi500139h. The average DNA polymerase requires about one second locating and binding a primer/template junction. The C-terminus region is thought to provide a checkpoint before entering anaphase, provide stability to the holoenzyme, and add proteins to the holoenzyme necessary for initiation of replication.[29] Polymerases η, ι

Relative to the shape of DNA polymerase’s binding pocket, steric clashes occur between the purine and residues in the minor groove, and important van der Waals and electrostatic interactions are lost Chem. 235: 2399–2403. The correct dNTP is then bound and the enzyme complex undergoes conformational changes of subdomains and amino acid residues. Pol β, encoded by POLB gene, is required for short-patch base excision repair, a DNA repair pathway that is essential for repairing alkylated or oxidized bases as well as abasic sites.

The same RecA-ssDNA nucleoprotein posttranslationally modifies the UmuD protein into UmuD' protein. PMID5946628. ^ "The Nobel Prize in Physiology or Medicine 1959". Cell Cycle. 3 (2): 114–116. doi:10.1128/mcb.23.8.2733-2748.2003.
